You may already know that Sayles' leaked draft was rather barmy. It began with Hammond sending a new character called Nick Harris ("an unemployed soldier of fortune") to Isla Nublar (now under the control of a Swiss company) to retrieve the shaving foam can stuffed with DNA samples that Dennis Nedry dropped way back in the first film.
Nick is caught, knocked out, and wakes up in a medieval castle in the Swiss Alps where the new owners of Isla Nublar are working on a hybrid dinosaur consisting of human, canine and dino DNA. Nick is recruited by the Swiss scientists to act as a drill sargeant to a pack of dinosaurs that they've managed to tame using radio signals.
Nick's dinos are put in armoured suits and sent to Tangier to rescue a 10-year-old girl from some terrorists. The mission is a bloody success, and Nick is next sent after a drug lord who is promptly attacked by dinosaurs while in his jacuzzi. At the climax of the film, the dino-soldiers turn on their Swiss masters.
